Parents and educators know that children with special needs have gifts and talentsâitâs just a matter of unleashing their full potential, and making sure that their parents and teachers have the right information, tools and support to help them. Thatâs where Special Education Guide comes in.
Answer Wiki. The ionic charge of oxygen is -2. You can tell because oxygen is in group number 6, so it has 6 valence electrons. Since it needs 2 more electrons to become neutral with a full outer shell of 8 electrons, its charge is -2 (since adding electrons gives a negative charge).
1 In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.  The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
